I had taken the patches you sent earlier and tried them on the SLES 11. There were a couple of collisions but not much. I am able to set the parameters in hardware handler with the patches. This also now allows multipath to handle path failures correctly where reservations are involved, aka honor reservations set on trespass command. I will do more testing but so far so good. I made one type cast change in scsi_dh_emc.c to avoid a warning char *p = (char *)params; I will look at your patches to make sure I reconciled the conflicts correctly.
